I had my trans rebuilt and I had my transmission shop put a Hayden thin transmission cooler.
I also now use Max Life synthetic transmission fluid for longer transmission life.
I do a drop and fill every 20,000 miles doing it twice to get an 8 quart change yearly

sorry, I asked the wrong question, I meant to ask if you have the towing hitch and if so if you know if it came on the vehicle new.

The reason being is from what I am learning is that Lexus installed transmission coolers on the vehicles that came from the factory with the towing package.

The standard and optional equipment changed over the years. In my model year (1999) the "Towing prep package" included the cooler but there was some pricey harness needed to add the lighting module. There may have been a "Towing package" that included the hitch and harness. I didn't get it.

Sorry for jumping in the middle of conversation here, but I am a bit lost ...

Is the enquiry about gathering info regarding model/yr/option to do research into a possible purchase or what ever then the conversation make sense.

Now on the other hand if the enquiry is .. does my vehicle have a cooler .. the answer is very simple .. just peek from the front air slot .. where the windshield washer reservoir is and if you see fins from an air cooler, you have one. Lexmex posted actual picture of this.
